Today we started the chapter on cloning and recombinant DNA technology.
We briefly discussed techniques in which plants an animals can be cloned and the reasons to do so. We devoted most of the time, though, to how DNA molecules are cloned. We introduced the concept and the basic steps of cloning DNA, starting by how DNA is cut by using restriction enzymes. We described how DNA from different organisms or species, if it has been cut with the same restriction enzyme, can be combined into single DNA molecules: Recombinant DNA.
